Abstract
An active suspension system and method for controlling the height of a vehicle. In an exemplary embodiment, the active suspension system receives information from one or more input sources, including both internal and external vehicle inputs, and uses that information to actively control the vehicle height. By doing so, the active suspension system can reduce aerodynamic drag on the vehicle and improve the vehicle's fuel economy, ride comfort, handling, and other aspects of operation. Some examples of external vehicle inputs that may be used include: short-range road and vehicle information, as well as long-range traffic, road and route information.
